Jopenmeraverse introduction

  1. 1. jopenmetaverse   Moving  to  3D  Web   Jitendra  Chauhan  Email:  jitendra.chauhan@gmail.com  
  2. 2. What  is  JOpenMetaverse?  •  A  library  to  interact  with  3d  virtual  world   simulators  (ex.  OpenSim).  •  Completely  wriHen  in  Java.  •  The  core  library  implements:   –  Simulator  Protocol  (Protocol  connecKng  to  OpenSim)   –  Networking  (based  on  HTTP  and  UDP)   –  Imaging  (Jpeg2000,  TGA  Images)   –  Android  SDK  CompaKble   –  3D  Rendering  (Currently  being  Developed)  
  3. 3. Why  JOpenMetaverse?  •  There  are  three  main  reasons  to  develop   JOpenMetaverse:   –  There  are  similar  libraries  wriHen  in  c#  and  c/c++,   however  there  is  no  such  library  in  Java.   –  There  is  no  similar  library  for  Android.   –  There  is  no  similar  library  for  Html5  /  WebGL   JOpenMetaverse  is  a  small  gi1  to  Java  Lovers!!!  
  4. 4. Goals   Android   JOMV  Desktop   HTML5  
  5. 5. JopenMetaverse   (a  collecKon  of  libraries)  jomv-­‐android     testclientjomv     jomv-­‐jclient     jopenmetaverse   jj2000-­‐android     jai_imageio    
  6. 6. JopenMetaverse   (Contd.)  Library   Descrip9on  jopenmetaverse   A  pla`orm  independent  core  library   implemenKng  Networking,  Protocol,   PrimiKve  Meshing  etc.  Jj2000-­‐android   Android  compaKble  jpeg2000  encoder   and  decoder.  Jai_imageio   Desktop  Java  based  Jpeg2000  image   encoder  and  decoder.  (not  compaKble   with  android).  Jomv-­‐android   Android  based  client  to  interact  with   OpenSim  Testclientjomv     Sample  client  to  interact  with  OpenSim  
  7. 7. Architecture   (Layered)  Desktop  based  OpenSim   Android  based  OpenSim   Client   Client   Simulator  Layer   Protocol  Layer   Resource  Layer   Pla`orm  Specific  Libraries

  10. 10. Features  •  ConnecKon   –  Login  in  to  OpenSim  Simulator   –  Baking  the  Appearance  (Wearing  Pants,  shirts  etc)  •  Avatars   –  Walking,  Flying,  Chaeng,  Friends  Making,  TeleporKng  •  Objects  (PrimiKves)   –  Searching  Inworld  PrimiKves   –  Create  /  Read  /  Update  /  Delete  PrimiKves  •  3D  Rendering   –  Baking  Terrain   –  PrimiKve  Meshing   –  PrimiKve  Rendering  
  11. 11. Design  PaHerns  •  Following  are  the  main  design  paHern  used   while  developing  the  library:   –  Observable  PaHern   –  Inversion  of  Control  (IoC)   –  Thread  Pooling   –  Assets  Caching  
  12. 12. Current  Challenges  •  3D  Rendering  for  Desktop  Clients   –  OpenGL  based  rendering  of  PrimiKves   –  OpenGL  Based  rendering  of  Avatars   –  AnimaKons   –  Touch  and  Interact  with  Inworld  Objects  •  InWorld  Sound  •  3D  Rendering  for  Android  Client  •  Memory  OpKmizaKons  •  CPU  OpKmizaKons
